RE SILIEN'I DRIVINGCONNECTION.

Application filetl lviay 11, 192 seri al iiio 458,572.

My invention relates to resilient driving connections, such as are interposed between and the driving wheels of railway vehicles and more par ticularly to driving connections of a. type similar to that disclosed in PatentNo. 1,059, 168, issued'on March 3, 1918to the esting.

as assignee, wherein tangentially disposed coil springs are, interposed between the driv iug and the driven members.

The object of my means for eliminating or compensating for such stresses as are imposed upon the springs as a result ofrelative axial or radial move ments between the driving and the driven members or as a result of centrifugal forces that are incidental to the operation of the driving mechanism. 7

Generally stated, my invention comprises means for supporting the ends of the springs in such manner that the springs shall have substantially universal movement in order that symmetrical relation may be maintained between the springs and their seats, thereby protecting the springs against strains which would otherwise be imposed upon them as a result of the abnormal conditions above enumerated.

As shown in the drawing,

Figure 1 is a view, in side elevation, of a port-ion ofa locomotive driving Wheel enibodying my invention, and

Figs. 2 and 3 are a plan a d a longitudinal sectional view, respectively, of a spring element built in accordancewith my invention.

For convenience of illustration, I have shown my invention as applied to a driving mechanism consisting of a locomotive wheel 6 that isdriven by means of a motor (not shown) through a quill member 6 that is provided with arms 7, the outer ends of which are so disposed as to lie substantially opposite the outer ends of the spokes 8 of the driving wheels 5. Helical springs 9 are interposed between the quill arms 7 and the spokes 8. i

Alternate spokes 8 are provided with hinge members 10 which have perforated eX- ensions, as shown in Fig. 3, through which hinge pins 11 extend. A. hinge member 12 is pivotally supported by the members 10 and 11 in the manner shown and is provided with extensions 13 for the reception of a hinge bolt 1 invention is to provide A seating block .15 is provided with perforated extensions 16 that, serve as a connection by. means of which it is supported upon the pin 1&1 and the hinge member 12, It will be seen that the seating block may move about the pin 14; as a pivot and also about;

the pin 11, such movements takingplace in planes that are at right angles to each other.

A clamping member li is provided for securely attaching the spring to theseating block. The spring may be either slid upon the seating block and the clamping member be then tightened or the spring maybe screwed "into place by reason of the screwbreadedformation of the outer face of the seating block and of the inner face of the clamping member.

At its opposite end, the spring is secured to the arm '7 that is provided with extensions 18 to serve for supporting a hinge member 19 by means of a bolt 20, and the hinge member 19, in turn, supports a seating block 21 by means of a hinge pin 22. The hinge arrangement at this end of the spring is substantially the same as that heretofore described for the opposite end thereof, and clan'iping ring 23 corresponds, in construction. to the clamping ring 17.

' The seatingblocks 15 and 21 are provided with weighted extensions 2 and 25 that serve to counteract the centrifugal force imposed upon the main portions of the springs 9. The counter-weights, however, form no part of the present invention.

' It is obvious that changes may be made in the general arrangement of the device without sacrificing those features which are essential to the successful operation thereof.
